Description

Technical Field

[0001] This utility model relates to a gate component, specifically a flat gate for oil fields. Background Technology

[0002] Oilfield flat gate valves are primarily used in high-pressure, high-temperature, and highly corrosive environments in onshore and offshore oil and gas fields, such as wellhead production trees and gathering pipelines. Made of high-strength alloy steel, they can withstand extreme pressure and sand-containing fluid erosion. They offer excellent sealing performance and resistance to corrosive media such as hydrogen sulfide. Features include a full-bore design to reduce flow resistance loss, low opening and closing force for easy operation, bidirectional sealing to ensure zero leakage, simple maintenance, and a long service life. A drive mechanism vertically raises and lowers the gate for rapid opening and closing, and when fully open, there is no stagnation zone to prevent sedimentation. They are particularly suitable for high-viscosity crude oil and conditions containing solid particles, making them a key control device for oilfield production.

[0003] In the prior art, application 202320697428.0 discloses a channel flat gate. This application relates to the technical field of gates and includes a support frame and a gate plate slidably disposed within the support frame. The support frame includes two parallel vertical rods and a bottom rod at the lower end. The vertical rods have grooves for the gate plate to slide up and down, and the bottom rod has slots for the gate plate to be inserted into. Two mud scrapers are provided on the gate plate, each abutting against the inner walls of one of the two grooves. The bottom rod has a receiving groove for accommodating the mud scrapers. A dirt-proof plate is slidably disposed within the slots. The bottom rod also has a first elastic element for driving the dirt-proof plate to slide upwards.

[0004] In existing technologies, poor sealing is common between the gate and the mounting frame, resulting in suboptimal performance of flat gates. Utility Model Content

[0005] In order to overcome the shortcomings of the existing technology, this utility model provides a flat gate for oil fields.

[0006] This utility model is achieved using the following technical solution: a flat gate for oil fields, comprising a gate, assembly frames on both sides of the gate, a sealing component between the assembly frames and the gate, an assembly boss on the top of the gate, an assembly hole on the assembly boss, a top traction rod for pulling the gate connected to the assembly boss by assembly bolts, the top traction rod and the assembly boss being further assembled by assembly bolts, a driving component, which is a driving cylinder, being assembled with the top traction rod, the driving cylinder driving the top traction rod and the gate to move, a sealing gap between the gate and the assembly frame, a sealing component, which is a sealing rubber ring, being provided within the sealing gap, and an inflation component on the sealing rubber ring.

[0007] The inflation component is a small air pump. A magnetic control valve is provided between the small air pump and the sealing ring. The small air pump is equipped with an inflation nozzle. The inflation nozzle and the sealing ring are assembled together. The small air pump inflates gas into the sealing ring.

[0008] An internal protective plate is provided on one side of the gate, and an installation position for installing the internal protective plate is provided on the gate. The internal protective plate is installed at the installation position by means of rivets.

[0009] The internal protective plate is provided with dotted protective protrusions, and a protective coating is sprayed on the dotted protective protrusions. The protective coating is an oil-repellent coating that protects against oil contamination and is a fluorinated coating.

[0010] The internal protective plate is provided with a main comb groove and a secondary comb groove, and multiple secondary comb grooves are provided on both sides of the main comb groove.

[0011] The gate is equipped with a liquid level monitoring component, which is a capacitor liquid level monitor, and the capacitor liquid level monitor is equipped with a monitoring probe.

[0012] Compared to existing technologies, this utility model features an inflatable sealing ring between the assembly frame and the gate, combined with a small air pump and a magnetic control valve. This allows for dynamic adjustment of the sealing ring's inflation. When sealing is required, the air pump inflates the sealing ring, improving the seal between the gate and the assembly frame. The drive cylinder directly acts on the top traction rod, effectively driving the gate for transmission. The internal protective plate uses a fluorine-coated oil-repellent treatment, combined with a dotted raised structure to effectively prevent oil adhesion, thus avoiding oil-containing contaminants from sticking to the gate. Primary and secondary flow channels are provided on the gate, allowing liquid to flow over the inner wall of the gate during lifting. A capacitive liquid level monitor provides real-time monitoring of the oil level, enabling monitoring of level fluctuations. Attached Figure Description
